Hazrat Abu Uqbah narrates that Hazrat Jabir bin Zaid explained the verse { فَمَنْ تَصَدَّقَ بِہِ فَہُوَ کَفَّارَۃٌ لَہُ } as follows: The command of expiation for sins is for the one who causes injury.

Hazrat Ubada bin Samit narrates that the Noble Prophet (peace and blessings be upon him) said: Pledge allegiance to me that you will not associate anything with Allah, you will not commit adultery, you will not steal. So whoever among you commits any of these acts and is punished for it, that punishment will be an expiation for his sins.

Hazrat Zakariya narrates that Hazrat Sha'bi said: This command is for the one who forgives.

Hazrat Abu Shurayh Khuza'i narrates that the Messenger of Allah, peace and blessings be upon him, said: If a person is killed or wounded, then he has a choice among three things. If he intends a fourth thing, then restrain his hand. These actions are: to kill (in retaliation), to forgive, or to accept blood money. Whoever chooses one of these and then returns (to seek revenge again), for him is the fire of Hell, in which he will abide forever.

Hazrat Wa'il narrates that I was present with the Messenger of Allah (peace and blessings be upon him) when a murderer was brought, being dragged by his straps. Upon this, the Messenger of Allah (peace and blessings be upon him) said to the guardian of the slain: "Will you forgive him?" He replied, "No." The Prophet (peace and blessings be upon him) said, "Will you accept blood money?" He replied, "No." The Prophet (peace and blessings be upon him) said, "Will you kill him?" He replied, "Yes." The Prophet (peace and blessings be upon him) repeated this three times. Then the Messenger of Allah (peace and blessings be upon him) said to him: "If you forgive him, he will bear the burden of his sin." The narrator says: So the man forgave him, and I saw the murderer dragging a piece of his strap; indeed, he had been forgiven.

Hazrat Abu Huraira narrates that a man committed murder during the time of the Messenger of Allah, peace and blessings be upon him. So this matter was presented before the Noble Prophet, peace and blessings be upon him. He, peace and blessings be upon him, handed him over to the guardian of the murdered person. The killer said, "O Messenger of Allah, peace and blessings be upon him! I did not intend to kill him." Upon this, the Noble Prophet, peace and blessings be upon him, said to the guardian, "If he is truthful and you kill him, then you will enter Hell." The narrator says: He let him go, that is, he forgave him, and the killer's hands were tied with a strap. So he left in such a state that he was dragging his strap, and he became known as 'the one with the strap.'

Hazrat Shu’bah says that I asked Hazrat Hakam and Hazrat Hammad about a free man and a slave who collided with each other and both died. Both of them said: In any case, the blood money of the free man is not upon the slave, and as for the blood money of the slave, it will be obligatory upon the family of the free man.

Hazrat Ikrimah and Ibrahim explained the verse: If the slain is from a people with whom you have a treaty, as follows: That man who accepted Islam in the land of war, then someone killed him: there will be no blood money (diyah) upon him, but expiation (kaffarah) will be obligatory upon him.

29849 - (And from) (1) Mughira from Ibrahim:“And if he belonged to a people between whom and you there is a treaty” [النساء: ٩٢] , they said: A man accepts Islam in the land of war, and another man kills him: there is no blood money upon him, but the expiation is due.

Hazrat Mughira narrates that regarding the saying of Allah, the Lord of Majesty: "And whoever kills a believer by mistake, then he must free a believing slave and pay the blood money to the heirs of the slain," about this verse, Ibrahim said: When a Muslim is killed, this ruling is for him and his Muslim heirs. And regarding the verse: "And if the slain is from a people who are enemies to you and he is a believer," he said: That Muslim man who is killed while his people are polytheists and there is no treaty between them and the Messenger of Allah (peace and blessings be upon him), then it is obligatory upon him to free a believing slave. And if he killed a Muslim whose people were polytheists and there was a treaty between that people and the Messenger of Allah (peace and blessings be upon him), then it is necessary for him to free a believing slave and pay the blood money to that people with whom there was a treaty between them and the Messenger of Allah (peace and blessings be upon him), and his inheritance will be for the Muslims. And his blood money will be for that polytheist people with whom there was a treaty between them and the Messenger of Allah (peace and blessings be upon him). Thus, the Muslims will inherit from him, and his blood money will be for his people, because they are the ones who will pay the blood money on his behalf.
